## 1、支持多数据源
4+
5+
数据源解析顺序:
6+
7+
- [ ] 对象@datasource
8+
9+
- [ ] 全局 @datasource
10+
11+
- [ ] 应用默认 @datasource
12+
13+
```json
14+
{
15+
// "@datasource": "db2" 全局
16+
"@post": {
17+
"User:aa": {
18+
"@datasource": "db2" // 对象
19+
},
20+
"User_address[]": {
21+
"@datasource": "db2"
22+
}
23+
},
24+
"User:aa":{
25+
"username":"test-3",
26+
"password": "233223",
27+
"state": 1
28+
},
29+
"ES_blog:a": {
30+
"@datasource": "elasticSearch",
31+
"title.keyword": "test-2"
32+
},
33+
"User_address[]": [
34+
{
35+
"user_id@": "User:aa/id",
36+
"addr": "ddd",
37+
"count@": "ES_blog:a/count"
38+
},
39+
{
40+
"user_id@": "User:aa/id",
41+
"addr": "ddd1",
42+
"count@": "ES_blog:a/count"
43+
}
44+
],
45+
"@explain": true
46+
}
47+
```
48+
49+
![image-20221213105328227](/Users/xy/Library/Application Support/typora-user-images/image-20221213105328227.png)
50+
51+
## 2、集成elasticsearch-sql
52+
53+
换成xpack, 也一样
54+
55+
应用导入: elasticsearch-sql-7.17.5.0.jar
56+
57+
## 3、apijson支持elasticsearch功能点
58+
59+
新增、修改、删除、查询
60+
61+
## 4、elasticsearch-sql不支持RLIKE
62+
63+
![image-20221213141141037](/Users/xy/Library/Application Support/typora-user-images/image-20221213141141037.png)
64+
65+
## 5、apijson支持字段 .keyword
66+
67+
```
68+
{
69+
"@datasource": "elasticSearch",
70+
"ES_blog:aa":{
71+
"title.keyword$": "%test-2",
72+
"content": "u-c-2",
73+
"url": "u-u-2",
74+
"postdate": "2008-12-11",
75+
"count": 1
76+
},
77+
"tag": "ES_blog",
78+
"@explain": true
79+
}
80+
```
81+
